Changes the start time and the interval between method invocations for a timer, using 32-bit signed integers to measure time intervals.
Namespace: System.Threading
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Function Change ( _
dueTime As Integer, _
period As Integer _
) As Boolean
public bool Change(
int dueTime,
int period
)
public:
bool Change(
int dueTime,
int period
)
member Change :
dueTime:int *
period:int -> bool
public function Change(
dueTime : int,
period : int
) : boolean
Parameters
- dueTime
Type: System. . :: . .Int32
The amount of time to delay before the invoking the callback method specified when the Timer was constructed, in milliseconds. Specify Timeout..::..Infinite to prevent the timer from restarting. Specify zero (0) to restart the timer immediately.
- period
Type: System. . :: . .Int32
The time interval between invocations of the callback method specified when the Timer was constructed, in milliseconds. Specify Timeout..::..Infinite to disable periodic signaling.
Return Value
Type: System. . :: . .Boolean
true if the timer was successfully updated; otherwise, false.
Remarks
The callback method is invoked once after dueTime elapses, and thereafter each time the time interval specified by period elapses.
If dueTime is zero (0), the callback method is invoked immediately. If dueTime is Infinite, the callback method is never invoked; the timer is disabled, but can be re-enabled by calling Change and specifying a positive value for dueTime.
If period is zero (0) or Infinite, and dueTime is not Infinite, the callback method is invoked once; the periodic behavior of the timer is disabled, but can be re-enabled by calling Change and specifying a positive value for period.
